Here you can see a brewing lab in an old design.
The mossy stones are supposed to represent that the laboratory has not been used for a long time, because so many experiments have been made in it and many explosions have taken place, the stones are already cracked.
Unfortunately there isn't much to see... This is more like an old dungeon or an old castle cellar with a few brewing stands, water and a Netherrack....
Mmh well am also the opinion of thebigsmileXD
Interesting methhode brewing stand to use
